  Title The migration of zebra and wildebeest between Tarangire National Park and Simanjiro Plains, northern Tanzania, in 1972 and recent trends Type Journal Article
  Year 1997 Publication African Journal of Ecology Abbreviated Journal Afr J Ecol  
  Volume 35 Issue 3 Pages 179-185  
  Keywords  
  Abstract In 1972, four aerial censuses were carried out to assess the annual migration of zebra and wildebeest between Tarangire National Park and Simanjiro Plains. About 6000 zebra and 10,000 wildebeest were in the Plains in the middle of the rainy season, in April. During the dry season in August the animals were concentrated in the Park. The migration from the Park to the Plains started at beginning of the rains, in November/December. Recent censuses by Tanzania Wildlife Conservation Monitoring (TWCM, 1991, 1995) indicate that an estimated 23,000 zebra and 11,000 wildebeest migrate into the Park from Simanjiro and other wet season areas. Encroaching cultivation is a threat to the migration corridors and sustainability of the ecosystem . Providing benefits from wildlife to communities around the park would safeguard the future of the wildlife.

  Title Bystander effects and the structure of dominance hierarchies Type Journal Article
  Year 2001 Publication Behavioral Ecology Abbreviated Journal Behav. Ecol.  
  Volume 12 Issue 3 Pages 348-352  
  Keywords  
  Abstract Prior modeling work has found that pure winner and loser effects (i.e., changing the estimation of your own fighting ability as a function of direct prior experience) can have important consequences for hierarchy formation. Here these models are extended to incorporate “bystander effects.” When bystander effects are in operation, observers (i.e., bystanders) of aggressive interactions change their assessment of the protagonists' fighting abilities (depending on who wins and who loses). Computer simulations demonstrate that when bystander winner effects alone are at play, groups have a clear omega (bottom-ranking individual), while the relative position of other group members remains difficult to determine. When only bystander loser effects are in operation, wins and losses are randomly distributed throughout a group (i.e., no discernible hierarchy). When pure and bystander winner effects are jointly in place, a linear hierarchy, in which all positions (i.e., {alpha} to {delta} when N = 4) are clearly defined, emerges. Joint pure and bystander loser effects produce the same result. In principle one could test the predictions from the models developed here in a straightforward comparative study. Hopefully, the results of this model will spur on such studies in the future.

  Title Toward a theory of dominance hierarchies: effects of assessment, group size, and variation in fighting ability Type Journal Article
  Year 1995 Publication Behavioral Ecology Abbreviated Journal Behav. Ecol.  
  Volume 6 Issue 4 Pages 416-423  
  Keywords  
  Abstract We introduce assessment to the analysis of dominance hierarchies by exploring the effect of an evolutionarily stable fighting rule when there is variation in resource holding potential (RHP) and RHP is not a perfectly reliable predictor of the outcome of a fight. With assessment, the probability of a linear hierarchy decreases with group size but can remain appreciable for groups of up to seven or eight individuals, whereas it decreases virtually to zero if there is no assessment. The probability of a hierarchy that correlates perfectly with RHP is low unless group size is small.

  Title Social grouping and maternal behaviour in feral horses (Equus caballus): the influence of males on maternal protectiveness Type Journal Article
  Year 2003 Publication Behavioral Ecology and Sociobiology Abbreviated Journal Behav. Ecol. Sociobiol.  
  Volume 53 Issue 2 Pages 92-101  
  Keywords  
  Abstract The risk of infant injury or mortality influences maternal behaviour, particularly protectiveness. Mares are found in bands with a single stallion or bands with more than one stallion in which paternity is less certain. We investigated maternal behaviour in relation to band type. Mares in bands with more than one stallion were more protective of their foals, particularly when stallions and foals approached one another. The rate of aggression between the stallion and foal was a significant predictor of maternal protectiveness, and mare protectiveness was significantly correlated with reduced reproductive success in the subsequent year. Mares that changed band types with a foal at foot, or had their band type experimentally altered, were more protective of their foal in multi-stallion bands than they were in single-stallion bands. Equids are unusual amongst ungulates in that infanticide and feticide have been reported. Both occur where paternity has been uncertain, and equid social structure is similar to other species in which infanticide has been reported. Stallions benefit from infanticide as the mare has greater reproductive success in the subsequent year. Stallion aggression is a significant modifier of mare behaviour and maternal effort, probably due to the risk of infanticide.

  Title The behavioural ecology of personality: consistent individual differences from an adaptive perspective Type Journal Article
  Year 2004 Publication Ecology Letters Abbreviated Journal Ecol. Letters  
  Volume 7 Issue Pages 734-739  
  Keywords Adaptive individual differences, behavioural ecology, behavioural syndromes, evolutionary game theory, life history strategies, personality differences, state-dependent dynamic programming  
  Abstract Individual humans, and members of diverse other species, show consistent differences in

aggressiveness, shyness, sociability and activity. Such intraspecific differences in

behaviour have been widely assumed to be non-adaptive variation surrounding

(possibly) adaptive population-average behaviour. Nevertheless, in keeping with recent

calls to apply Darwinian reasoning to ever-finer scales of biological variation, we sketch

the fundamentals of an adaptive theory of consistent individual differences in behaviour.

Our thesis is based on the notion that such .personality differences. can be selected for if

fitness payoffs are dependent on both the frequencies with which competing strategies

are played and an individual`s behavioural history. To this end, we review existing models

that illustrate this and propose a game theoretic approach to analyzing personality

differences that is both dynamic and state-dependent. Our motivation is to provide

insights into the evolution and maintenance of an apparently common animal trait:

personality, which has far reaching ecological and evolutionary implications.

  Title Effects of territorial intrusions on eavesdropping neighbors: communication networks in nightingales Type Journal Article
  Year 2004 Publication Behavioral Ecology Abbreviated Journal Behav. Ecol.  
  Volume 15 Issue 6 Pages 1011-1015  
  Keywords  
  Abstract Animal communication often occurs in communication networks in which multiple signalers and receivers are within signaling range of each other. In such networks, individuals can obtain information on the quality and motivation of territorial neighbors by eavesdropping on their signaling interactions. In songbirds, extracting information from interactions involving neighbors is thought to be an important factor in the evolution of strategies of territory defense. In a playback experiment with radio-tagged nightingales Luscinia megarhynchos we here demonstrate that territorial males use their familiar neighbors' performance in a vocal interaction with an unfamiliar intruder as a standard for their own response. Males were attracted by a vocal interaction between their neighbor and a simulated stranger and intruded into the neighbor's territory. The more intensely the neighbor had interacted with playback, the earlier the intrusions were made, indicating that males eavesdropped on the vocal contest involving a neighbor. However, males never intruded when we had simulated by a second playback that the intruder had retreated and sang outside the neighbor's territory. These results suggest that territorial males use their neighbors' singing behavior as an early warning system when territorial integrity is threatened. Simultaneous responses by neighboring males towards unfamiliar rivals are likely to be beneficial to the individuals in maintaining territorial integrity.
